Description

The User Submitted Posts plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes in versions up to, and including, 20230901 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
